pPSI digestion

pPSI dephosphorylation

After 2 hours, add 1.5µL of Alkaline Phosphatase (AP) and let it 1 hour.

Then, inactivation of AP at 65°C during 15 minutes.

We've made a electrophoresis to check the digestion.

Ligation of BBa_K517003, BBa_K762100, and p cola in pPSI

And let it in the freezer during 3 hours.

Transformation in competent E.coli DH5 Alpha

After 3 hours, take out the ligation tubes and add 100 µL of competent DH5 Alpha in each tube.

Then procede to the transformation protocol.

- 20 minutes at 4°C

- 2 minutes 30 seconds at 42°C

- 2 minutes at 4 °C

- Add 0.9 mL of LB into the tubes

And finally put it in a incubator at 37°C during 30 minutes

Transformation of pPS3 in DH5 alpha

We add 100 µl of DH5 alpha in the pPS3 ligation tube and we follow the classic protocol of transformation.
